The model 6300-M3 comes with an RS232 interface. This interface is mainly used to download profiles from a computer. Connect Power and the Remote, connect the Pitot and Static outputs to the aircraft, and the 6300-M3 is ready for use. It’s high accuracy and ease of use make it the ideal Pitot Static Tester.
The model 6300-M3 top panel (Figure 2.1) provides easy access to all the connections. AC INPUT connector : This is a 3-pin male circular connector. An AC power cord is provided with the 6300-M3. The circular connector end of the power cord needs to connected here. The power requirement of the 6300-M3 is 90-260 VAC, 47-440 Hz with a maximum power consumption of 300 VA.
Page 12
Remote Unit connection: The 6300-M3 is provided with a 50 foot remote cable to connect to the Remote unit. The male end of the remote cable is connected here on the top panel. The female end of the remote cable is connected to the Remote unit.

“profiles” from a computer. Other remote communication with the 6300-M3 is also possible through this interface. Figure 2.2 shows the RS232 connector with the panel removed. For more details on downloading profiles, please refer to Section 4.
Page 14
In the event that the 6300-M3 is in-operable due to a malfunction or due to loss of power, it is possible to vent the Static system manually. This is done using the metering valve labeled “Static Vent”, located on the top panel, to the left of the DC On/Off switch. This valve is a positive shut-off valve.
4 lines of 40 characters each. There are five function keys just below the display. NEXT SCREEN and PREVIOUS SCREEN are used to move between the different operating screens of the 6300-M3. At present there are only three upper level operating screens : Main, Calibrate and Self test.
Page 18
TARGET VALUE KEYS : There are typically 3 parameters that the 6300-M3 controls - Altitude, Climb and Airspeed. Each parameter has its own target value key. The Pt/AIRSPEED key is used to select Pt or Airspeed target value entry, the RATE/CLIMB key is used to select Climb value entry, and the Ps/ALTITUDE key is used to select Ps or Altitude value entry.
The 6300-M3 is typically used to calibrate and check air data instruments like altimeters, climb indicators, and airspeed/ Mach indicators on an aircraft. It is also used to leak-check the Pitot/ Static system of an aircraft. This section will explain how to use the 6300-M3 to perform these functions.

Remote unit and the main unit. Please abort and contact the factory. If GO is pressed after ENTERing the value, the 6300-M3 will try to achieve this new target value ONLY IF the Pitot output is in the CONTROL mode. Therefore, it is desired that both Pitot and Static values be entered so that both are blinking before the GO key is pressed.
Target Value Jog Each of the three target values can be jogged up or down in small increments by using the arrow keys. This is done to help the operator achieve a perfect reading on the instrument in the aircraft, by bumping the set-point in small increments. To jog a value, select the value by pressing the appropriate target value key and then use the arrow keys.

The selected mode is displayed on the screen and blinks until the GO key is pressed. The new mode will not become effective until the GO key is pressed.
Page 33
Following the Equalization process, only when the actual value on the Static output is less than 2000 feet from Ground and the Pitot output is less than 150 knots, the 6300-M3 will automatically inject a small vacuum on the Static output and a small pressure on the Pitot output.
“Control” takes place within 2000 feet of Ground and 150 knots. LEAK SCREEN Although most of the operation of the 6300-M3 will be performed while in the Main Operating Screen described above, at times, the Leak Screen is also accessed.
Page 35
While in the Static Leak Screen, if the leak ever exceeds 2000 ft/min, the 6300-M3 will automatically trip out of the Leak mode and revert back to Control mode. It will then display a message as follows: Static leak exceeds 2000 ft/min.
When both Pitot and Static outputs are simultaneously put into Leak mode, then the leak screen displays the leak values in a timed-leak format as shown below. The sample screen shown below assumes the following: a. Units are set to knots and feet b.
Page 37
ENTER. The screen will appear as below. Change the 2 leak-timer value if desired, using the Arrow keys. The leak-timer value must be changed before the elapsed time reaches 58 seconds. The 2 leak-timer value can be adjusted between 2 and 19 minutes. 100.0 knots 0 ft/min.
Page 38
value leaked to 99.5 knots and the accumulated leak in 1 minute was -0.5 knots, since the knots value at the start of the leak check was 100 knots. The second line also shows that at the end of 1 minute, the altitude was at 14965 feet and the accumulated leak in 1 minute was -35 feet, since the altitude was at 15000 feet at the start of the leak check.
As part of the start up procedure, it is recommended that a Self Test be performed on the 6300- M3. Before performing the Self Test you must follow the start up procedure explained in section 3.1. The Main Operating Screen must be displayed on the Remote unit. There should be no errors displayed on line 4 of the display.
remaining tests is displayed as shown below. Pump section OK Ps control system OK Pt control system OK. Tests successful. After the tests have been completed successfully, press the CANCEL key to return to the Main Operating Screen. If any of the tests fail, then note the failure, turn OFF the unit and contact the factory. FUNCTION SELECT SCREEN There are 10 different functions that can be performed.
3.5.0 FUNCTION 0 : IEEE ADDRESS This function allows the user to enter a valid IEEE-488 address for the 6300-M3. This address is meaningful only if the “IEEE” option is provided on the 6300-M3. A valid address between 1 and 30 may be entered on the screen shown below.
If the target value exceeds any of the limits, an error is generated. The Actual values are also checked when the 6300-M3 is in the “Control” mode. If any of these limits is exceeded by a pre-defined amount, an error will be generated and the 6300-M3 will revert to “Measure”...
setting for this limit is 1.0. 4. Max. Feet : This limit is usually set to the maximum altitude that the aircraft instruments can tolerate. The maximum value is 100,000 and the minimum is 0. A typical setting for this limit is 50,000. 5.
This indicates that the current profile point is ready for execution and awaiting the “GO” key to be pressed. When the “GO” key is pressed, the 6300-M3 will execute the profile point, i.e. it will change to Control mode and move towards the desired targets.
3.5.5 FUNCTION 5: SETUP PROFILES This function is used to load profiles into the 6300-M3 from a PC. A full explanation of how to load profiles into the 6300-M3 is provided in Section 4.. The following screen will come up when Function 5 is selected.
The “Set Ground” function is used to indicate to the 6300-M3 the ambient “Ground” pressure. Before connecting the 6300-M3 to the aircraft, just after the Self Test has been performed, it is recommended that this function be invoked. The Pitot and Static ports must still be open to ambient when using this function.
Page 47
If an altitude encoder is electrically connected to the Encoder interface connector on the top panel of the 6300-M3 (under the Interface Connectors panel) and is pneumatically connected to the Static output of the 6300-M3, then 10-bit code on line 2 and flight level on line 3 will correspond to the altimeter reading.
4.1 WHAT IS A PROFILE. A profile is a set of up to 50 points that tell the 6300-M3 what you would want it to do at each point. Each point consists of 7 parameters: 1) Pitot units, 2) Pitot mode, 3) Pitot target value, 4) Static units, 5) Static mode, 6) Static target value and 7) Static rate (Climb) target value.
Page 49
Rate target value In the sample profile, Row 3, which is the first point in the profile, tells the 6300-M3 to go in Control mode to 100 knots on the Pitot side, and in Control mode to 0 feet at 6000 feet/min on the Static side.
12 characters. On Row 2, middle cell, replace “11” with a profile number between 1 and 20 that you would like this profile to be saved as, in the 6300-M3. Do not change row 2 right-most cell. In rows 3 through 50, change the cells as per the points you want to generate in your test.
Your profile has been created. 4.3 SETTING UP HYPERTERMINAL You download a profile into the 6300-M3 using the Hyperterminal program. At first you need to setup Hyperterminal. You only need to do this once.
To verify that the 6300-M3 file is setup in Hyperterminal, select “All Programs” from the desktop, select “Accessories”, select “Communications”, select “Hyperterminal”. The “6300-M3” icon should appear. If it does not appear then you will need to repeat steps 1 and 2 above.
PC as your profile. 4.5 EXECUTING A PROFILE On the 6300-M3, select Function 4: Execute profile. On line 4 on the Main screen, a profile number is required to identify the profile. This number is x.y where x is the profile number and y is the point number within that profile.
Page 54
50 points can be loaded as profile 1 and the remaining 30 points can be loaded as profile 2. When profile 1 has been completed at point 1.50, the 6300-M3 will stay at that point until the next command. The user can start profile 2.1 and execute the 51st point and continue through...
8. If Pitot has a significant leak (more than 5 knots/min.) then first try and find the leak while the 6300-M3 is in the Leak screen. If you lose all airspeed while searching for the leak, cancel out of the Leak screen and go back to Step 7 and continue to search for the leak.
Page 56
Go back to Ground and go through the leak test process shown above, to find and fix the leak before proceeding further. It may be helpful to keep a copy of the procedure, shown in Figure 5.1, with the 6300-M3 to assist the operator while using the 6300-M3.

Set the BARO adjust on the aircraft to 29.92 or 1013 or Standard. STEP 1: SELF TEST Turn ON 6300-M3 and check / adjust leak timers in timed-leak screen (put both Pitot and Static in Leak). ). After checking / adjusting leak-timers, press CANCEL to return to Main Screen.
4.0 inHg abs. The 6300-M3 has a drift of typically 0.005 %FS per year. Therefore it needs to be calibrated once a year to perform adequately as a calibration standard for air data equipment.
Step 2. Turn on the 6300-M3 and allow it to warm up for about 30 minutes. Change the units to “PsinHg” on the Static side and “PtinHg” on the Pitot side. Refer to section 3.2.3 on how to change units.
Step 2. Turn on the 6300-M3 and allow it to warm up for about 30 minutes. Change the units to “PsinHg” on the Static side and “PtinHg” on the Pitot side. Refer to section 3.2.3 on how to change units.
Page 61
Step 4. Generate a pressure of 100.000 inHg absolute, allow the pressure to stabilize for 2 minutes and take the reading on the Pitot side (PtinHg) of the 6300-M3. This is the second of your “Before” calibration adjustment reading. It will indicate the zero plus slope drift since the previous calibration.
Page 62
Step 8. On the keypad of the remote unit, press “PREV SCREEN”. The display will return to the Main Screen. If you press “CANCEL” the calibration adjustment will become void. Step 9. Turn the 6300-M3 OFF, wait 30 seconds and then turn it back ON. The calibration adjustment is now complete for the Pitot port.
